#1285288 — [PATCH] Staging: speakup: varhandlers: cleanup of function spk_get_punc_var

This patch does the following:
* changed the complicated if statements to simple case statements
* in case of E_DEFAULT, no need to return error as ERESTART,
because this is the user asked for. Hence function should return success.
* ret variable is 0 always, hence removed it.
* removed one ternary operator, as it was always returning the status value only,
and hence removed the status variable too

That becomes 4 different changes. Please break them into separate
patches.

It's cleaning up one function so you could argue that it's just one
thing.  Sometimes it's actually harder to review when a patch is broken
into ultra tiny junks.

yes Dan, this is my point too.
I was planning to cleanup many function in speakup.
If I will be breakup in to such a small chunk, it will problem for both of us.
The best I can do is to hide the details in description and just say
clanup there.
I am open to suggestions.

Saurabh

Then maybe that should have been mentioned in the commit message along
with mentioning point wise the different changes made.
